Why is Digital Thermometer Better than Mercury Thermometer?
The mercury thermometer has been used for temperature measurement in our life quite a historic time. With technology development, a digital thermometer is taking over the mercury thermometer today. How come the digital thermometer is better than the mercury thermometer? Here we come up with three reasons to analyze.
1. Digital thermometer is faster on temperature measurement result providing
The digital thermometer gauges our body temperature by using electronic circuits. When the probe is heated by our body, it energizes the circuits with electric power and strengthens the amperage. The higher our body temperature is, the more powerful the electric flow is, and the stronger the amperage is. When the amperage is switched into data and shows on the thermometer screen, we can read the results immediately. The whole process is very fast in only 15-20 seconds. It works in the same theory as IR temperature gun. On the other hand, while, the mercury thermometer has to be 10-15 minutes so that we can see the results on the calibration tube.
2. Digital thermometer is more accurate for temperature measurement
Furthermore, digital thermometers are more accurate on body temperature than the mercury thermometers. The accuracy of a digital thermometer could be 0.1 ℃ with 0.01 ℃ errors. There is a thermocouple sensor installed in the probe of the digital thermometer. It is highly sensitive to temperature and will calculate it with accurate data on the screen. As to the mercury thermometer, whose operational principle is mercury expanding under heat, the accuracy is not as good as digital thermometers.
3. Digital thermometer is safer for use on house living
Since we would have to take our body temperature frequently at home these days, the digital thermometer is the best device because it is safe for usage. The mercury thermometer is made of glass and mercury. As we know, it is fragile. Moreover, mercury is a toxic chemical, which will contaminate human bodies after released. It is not easy to clean up if the thermometer is damaged and mercury splashes. The digital thermometer is made of hard plastic, PET material, and rubber. Same as the infrared thermometer, it is safe for our bodies. What’s more, it is not easy to break.
From the three reasons above we can see that digital thermometer is better than a mercury thermometer on faster and more accurate measurement results providing, safer for use in our life. Taking our body temperature at home every day is necessary because it is a good way to avoid Covid-19 from spreading. All in all, you may leave your comments if you have any opinion about the analysis above.

A face mask is good equipment to keep us from pollutions and harmful particles in the air. Since the Covid-19 outbreak, we are more and more concerned about our respiratory health. Here we would like to teach you three ways on how to make DIY face masks with simple materials. With these methods, we can make our beautiful unique face mask at home.
1. How to make scarf face mask
Our scarf and bandana are great materials to make face masks. Firstly, pick a clean smooth scarf to tile on the table. Fold it into layers from up-down and bottom-top, make it as a strap. For better filtering effect sake, we’d better embed a cotton yarn layer inside. Remember the strap height should be covered from your nose to your chin. Place two rubber bands on each side and fold the two sides to the middle. Tuck on end to the other and smooth the surface. Now a scarf face mask is completed. Try it on and make it comfortable on your face.
2. How to make a T-shirt face mask
We can make face masks with our T-shirts. Our wear out T-shirt, make sure no holes on it, or new purchased T-shirt if you don’t mind cutting it up, is great for making face masks. Choose the 100% cotton one would be better because it is more effective for filtering. Cut the bottom of the T-shirt in the height of the distance from your nose to your chin. Normally, the distance would be 7 to 8 inches for adults and 4 to 6 inches for children. Cut it into 6 to 7 inches and left two strings on the top and the bottom left the rest part enough for the coverage of your face. Cut the two strings so that they can be knot around your head and neck. Sew a filtering layer under the face mask. A T-shirt face mask is completed. It’s very simple.
3. How to make cloth face mask
If you want to make your favorite style face mask in beautiful colors and patterns, this method would be delightful to you. On doing this we will need a sewing machine. Choose a piece of clean cloth with the colors and patterns you like, and fold it into two or four layers. Cut the cloth into the style shape you like, here we take the surgical mask style as an example. We cut the cloth in 10*6 inches cube, smooth it on the table with the pattern side on the bottom and the material side towards you. Same as we mentioned, we embed a filtering layer in the middle. Fold the top and bottom side in about 0.25 inch and stitch with the sewing machine. Hem along in 0.5 inches and stitch the left and right sides, make two long strings on each side for knotting. A new cloth mask is completed.
These are the three simple methods for making DIY face masks at home. One thing we have to remember is that DIY face masks made ourselves are not meet the CDC standards, which requires our frequent changing, washing, and disinfection. Besides, we may also go online shops for KN95 face mask or disposable surgical mask. No matter what, we should always remember to wear a face mask outdoors. Personal health should be always in the first place.
